Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile wiring harness accessories, in particular to a protective shell used for preventing a sensor wiring harness from being exposed. Background Art
[0002] The steering gear sensor harness is a key component in the automotive electric power steering system. It is mainly responsible for signal transmission between the torque angle sensor and the electronic control unit (ECU). The sensor harness is responsible for transmitting angle and torque signals. These signals are received by the electronic control unit and used to control the motor current to provide variable steering assist. The harness usually includes multi-core shielded signal wires or multiple single-core loose wires to ensure accurate signal transmission.
[0003] In the sensor wiring harness, a portion is exposed between the wiring harness terminal and the bellows. Currently, the sensor wiring harness is installed on the housing with a simple sheet metal bracket, which will cause the connection between the wiring harness and the EPS assembly housing to be partially exposed. This exposed portion of the wiring harness is at risk of damage, which reduces the life of the wiring harness. In addition, there is no sealing structure at the installation location of the sensor wiring harness, which will cause air leakage and affect the air tightness of the EPS electric steering assembly. Therefore, a protective shell is urgently needed to prevent the sensor wiring harness from being exposed to solve the above problems. Utility Model Content
[0004] (1) Technical problems solved
[0005] In response to the shortcomings of the existing technology, the utility model provides a protective shell for preventing the sensor wiring harness from being exposed. It has the advantages of good protection, etc., and solves the risk of damage to the wiring harness when it is exposed, which reduces the life of the wiring harness. In addition, there is no sealing structure at the installation part of the sensor wiring harness, which will cause air leakage and affect the air tightness of the EPS electric steering assembly.
[0006] (2) Technical solution
[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a protective shell for preventing the sensor wiring harness from being exposed, comprising a sensor wiring harness bracket and a steering gear assembly shell, a locking assembly being provided on the outside of the sensor wiring harness bracket, the locking assembly comprising a holder fixedly connected to the bottom of the sensor wiring harness bracket, a bayonet being provided inside the holder, a sleeve being provided on the outside of the holder, and a clamping block being rotatably connected inside the sleeve.
[0008] The beneficial effects of the utility model are:
[0009] This protective shell, used to prevent the sensor harness from being exposed, is installed on the EPS assembly housing by compacting it with a rubber plug, ensuring a gap-free connection with the assembly. This significantly reduces gas leakage from the sensor harness, thereby improving the airtightness of the entire EPS assembly.
[0010] The protective shell for preventing the sensor wiring harness from being exposed uses a locking assembly to clamp the corrugated tube at one end of the wiring harness into the cavity of the wiring harness bracket protective shell through a snap mechanism, and the other part of the wiring harness bracket protective shell is compacted and connected to the shell with a rubber plug, so that the exposed part of the wiring harness is protected, the risk of damage to the wiring harness is reduced, and the service life of the wiring harness is increased.
[0011] On the basis of the above technical solution, the present invention can also be improved as follows.
[0012] Furthermore, the block has a wedge-shaped shape.
[0013] Furthermore, there are two bayonet holes, and the clamping block extends to the inside of the bayonet holes.
[0014] The beneficial effect of adopting the above further solution is that the buckle is pressed inward to support the concave and convex wave-shaped portion of the corrugated tube, so that the wire harness is fixed and cannot move.
[0015] Furthermore, a screw is provided inside the sensor harness bracket, a connecting hole is provided inside the steering gear assembly housing, and the screw is threadedly connected in the connecting hole.
[0016] The beneficial effect of adopting the above further solution is that the sensor harness bracket is fixedly connected to the steering gear assembly housing by means of screws.
[0017] Furthermore, a rubber plug is provided on the outside of the sensor harness bracket.
[0018] The beneficial effect of adopting the above further solution is that the rubber plug is used to ensure that there is no gap at the connection.
[0019] Furthermore, a wiring harness corrugated tube is inserted into the interior of the locking assembly.
[0020] The beneficial effect of adopting the above further solution is that the wiring harness is protected by the wiring harness corrugated tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The utility model includes a sensor harness bracket 1 and a steering gear assembly shell 2. A locking assembly 3 is provided on the outside of the sensor harness bracket 1. The locking assembly 3 includes a holder 31 fixedly connected to the bottom of the sensor harness bracket 1. A bayonet 32 is provided inside the holder 31. A sleeve 33 is provided on the outside of the holder 31. A block 34 is rotatably connected to the inside of the sleeve 33. A harness bellows 4 is inserted into the locking assembly 3 to protect the harness.
[0028] The shape of the block 34 is wedge-shaped, and there are two bayonet sockets 32. The block 34 extends to the inside of the bayonet socket 32. The block 34 will press against the inner wall of the bayonet socket 32. When the sleeve 33 is moved, the block 34 will be squeezed inward to press against the concave and convex wavy part of the corrugated tube, thereby fixing the wiring harness inside the corrugated tube 4 and making it unable to move. By setting glue at the connection between the sleeve 33 and the holder 31, the sleeve 33 will be unable to move after the glue solidifies, thereby improving the stability of the wiring harness connection.
